Title: Auto-stop mechanism for a tape recorder
Inventor: ISHIKAWA MITSUO
IPC: G11B15/093
Filed: 1989-08-22
Abstract: An auto-stop mechanism for a tape recorder comprises a sensor 9 having a forked cam aperture 9e. The forked cam aperture 9e has an abutting portion 9h. The sensor 9 is rotatable in connection with the direction of taking-up the tape. A sensor lever 7 which is rotatable regardless of tape direction has a pin 7b. The pin 7b engages in the forked cam aperture 9e. When the taking-up of the tape ends and the sensor 9 stops rotating, the pin abuts against the abutting portion of the cam aperture to limit the swinging stroke of the sensor lever, thereby stopping the tape recorder. In the auto-stop mechanism, there is provided a mechanism 6c, 7c for confirming the disappearance of the rotating force of the sensor by slightly rotating the sensor lever a little after the pin has collided with the abutting portion, thereby preventing erroneous auto-stop actuation if the pin catches the abutting portion during tape reversal or if the tape becomes slack. <IMAGE>

Title: Respirometer
Inventor: COOPER ROGER
IPC: A61B5/091
Filed: 1989-11-22
Abstract: A respirometer for recording exhalation parameters has a duct (12) with a restricted outlet (14), through which, in use, expired air is blown to create a pressure within the duct representative of the flow rate. A pressure sensitive transducer (15) communicates with the interior of the duct (12) and produces electrical output signals which vary with the pressure of expired air in the duct. An automatic signal processing unit (20, 21, 22) produces from the varying electrical signal generated by the pressure transducer (15) signals representing one or more parameters characterising the exhalation which can be displayed on a screen (16). These parameters can also be stored in a memory (25) from which they can be read by external equipment. <IMAGE>

Title: Fluid pressure retarder
Inventor: KANEDA NAOKI
IPC: B60T10/02
Filed: 1991-04-17
Abstract: A fluid pressure retarder for acting on a rotary shaft (2) which is rotated with rear wheels of a vehicle is of the type with a permanent store of fluid and a reservoir tank (10) is in fluid communication with the retarder and is subject to air pressure which is controllable by means (11-21) to vary the degree of braking caused by the retarder. A valve (11) selectively connects the tank (10) to atmosphere through a check valve (20) with a preset bias to set a first, low, pressure or to a further tank (12) through a restrictor (17) to set a second, higher pressure. Because of the restrictor (17) the response of the retarder is slower in the latter case and enables the driver of the vehicle to distinguish between the two conditions. <IMAGE>
